33 How, then, did we not answer humbly enough? If he demand tribute, we do not refuse it. The lands of the Church pay tribute. If the Emperor wants the lands, he has the power to claim them, none of us will interfere. The contributions of the people are amply sufficient for the poor. Do not stir up ill-will in the matter of the lands. Let them take them if it is the Emperor's will. I do not give them, but I do not refuse them. They ask for gold. I can say: Silver and gold I do not ask for. But they stir up ill-will because gold is spent. I am not afraid of such ill-will as this. I have dependents. My dependents are Christ's poor. I know how to collect this treasure. On that they may even charge me with this crime, that I have spent money on the poor! And if they make the charge that I seek for defence at their hands, I do not deny it; nay, I solicit it. I have my defence, but it consists in the prayers of the poor. The blind and the lame, the weak and the old, are stronger than hardy warriors. Lastly, gifts to the poor make God indebted to us, for it is written: “He that gives to the poor, lends to God.” The guards of warriors often do not merit divine grace.
